EDWIN H. CARSWELL, OF HACKENSAOK, NEWJERSEY, ASSIGNOR TO ELIZABETH C. SEAMAN, OF NEW YORK, N. Y.

MILK-CAN.

SPECIFICATION forming part of Letters Patent No. 712,993, dated November 4, 1902.

`Application filed November 26, 1901. Serial No. 83,716. (No model.)

To @ZZ whmn t may concern:

Beit known that I, EDWIN H. CAEsWELL, a citizen of the United States, and a resident of Hackensack, Bergen county, New Jersey, have invented certain new 'and useful Improvementsin Milk-Cans, of which the following is a specification.

My invention relates to jacketed milk-cans in which the can cover or closure is combined with a large insulated air chamber or dome, whereby the closure portion of the can may be efficiently insulated,and at the same time provision may be made, if necessary, for ventilat-ion.

In the accompanying drawingsI have shown in more or less detail a can in which my invention is embodied.

In the drawings, Figure I is a side elevation of a can embodying myinvention. Fig. II is a vtransverse section through the can-'body with thev cover removed; and Fig. III is a broken-away sectional detail view of the upper. portion o the can, 'showing the cover in place. I

In the drawings, a. is the body of the milkcontaining can or inner chamber, which is surmounted by a breast b and neck c of any desired construction. Surrounding the canbody a is a metallic casing e, provided with a suitable bottom f, preferably of the form shownthat is to say, a bottom provided with a depending flange g, which may be riveted between a stiening-hoop h and the casing e. The top of the casing e is or may be provided with a suitable angular breast-hoop fi, having in its edge a retaining-hoop j, which is soldered to the can-breast b and to the breasthoop t'. A ring t is interposed between the outer and inner cans, being mounted on the junction of the breast andi the cylinder of inner can. between the two cans. g

A suitable non-conducting body k, such as asbestos, is provided between the inner or milk-containing can a. and the outer can or casing e. A combined air-chamber and insulating-cover is adapted to cooperate with the milk -containing portion of the can. This combined air-chamber and insulating-cover is shown in the present instance as a domeshaped casing Z,`containing a dome-shaped casing m. Secured to the inner casingm is a suitable flange o, which is adapted to close the mouth of the can after the manner of the This4 ring nearly iills the space ordinary can-cover. The inner casing fm.' is provided with an outwardly-projecting ange, so that the two chambers form between them a space for the reception of the asbestos or other non-conducting body o. A suitable stifEening-hoop p may be embraced by the rolled-up lower edge of lthe outer casing.

The outer casing e may be providedfwith any desired type of handle, and the combined cover and air-chamber may be likewise provided Wth one of the same handles. In the present instance I have shown a handle s of what is known as the Philadelphia pattern.

It will be obvious that the asbestos body 7c protects the body portion of the can from the warming or chilling iniiuence ofy the outside atmosphere and that the combined air-chamber and cover protects the upper portion of the can from similar influence.

Having described my invention, what I claim, and desire to secure by Letters Patent,

l. In a jacketed milk-can, the combination of a suitable milk-cana having a neck and breast, an exterior metallic casing surround-- ing and secured to the said can and terminating at or about the joint betweenthe'neck and the cylinder, a cover comprising outer and inner rigid casings, the outer casing being adapted to surround the outer casing of the cylindrical portion of the canand the inner casing being adapted to rest upon the outer cylindrical portion of the can, the said inner casing being provided with a closure for the can-mouth.

2. In a jacketed milk-can, the combination of a suitable lmilk-can a having a neck and a breast and a cylinder with a joint between the breast and the cylinder,a ring surrounding the said joint between the breast and the cylinder, an exterior metallic casing surrounding and secured to the said can and terminating at or about the joint between the breast and the cylinder, a cover comprising outer and inner casings, the outer casing projecting beyond the inner casing, and the inner casing being adaptedto rest upon the outer cylindrical portion of the can, the said IOO inner casing being provided with a closure
